SACRAMENTO, Calif. (AP) — Gov. Jerry Brown's plan to deal with a federal court order to lower the state's prison population faces an uncertain future in the state Legislature because of opposition from key members of his own political party. If lawmakers fail to reach agreement quickly, they risk having federal judges override state law and take the step that is opposed by the governor, lawmakers and law enforcement — releasing 9,600 felons by the end of the year. Brown has support from three of the four legislative leaders of both political parties. But Senate Democrats are pushing their own competing solution. They plan to present their alternative Wednesday to Brown's proposal to spend more than $300 million this year to temporarily rent thousands of prison cells.
